ʻO nā ʻano a me nā ʻano o nā kiwi hoʻohālikelike electro-hydraulic no nā mīkini hana
Electro-hydraulic proportional valves proportional flow valves proportional pressure valves proportional pressure valves proportional directional valves. Wahi a nā hiʻohiʻona o ka hana hydraulic o nā mīkini hana, ʻelua ʻano o nā ʻāpana electro-hydraulic proportional valves: ʻo kekahi he spiral cartridge proportional valves, a ʻo kekahi he slide valve proportional valves.

He mea ia e hoʻopaʻa ai i ka pahu pahu electromagnetic ma luna o ka pahu hui kaapuni ʻaila ma o ke kaula. Loaʻa i ka valve cartridge spiral nā hiʻohiʻona o ka noi maʻalahi, mālama paipu a me nā kumu kūʻai haʻahaʻa, a me nā mea ʻē aʻe.
Hoʻohana maʻamau ʻia ka pāpaʻi hoʻohālikelike ʻano ʻano ʻāpana ʻelua, ʻekolu, ʻehā a me nā ʻano multi-pass, ʻelua mau ala like ʻole ka nui o ka valve throttle, ua hui pinepine ʻia me nā mea ʻē aʻe e hana i ka valve composite, kahe, kaomi mana; ʻO ka valve proportional ʻekolu-ʻaoʻao ka nui o ka puʻupuʻu hoʻohaʻahaʻa hoʻohaʻahaʻa proportional, a he valve proportional nō hoʻi ia i hoʻohana hou ʻia i ka ʻōnaehana hydraulic mechanical mobile, ʻo ia ka mea nui e hana i ka ʻaila pailaka o ka hydraulic multi-way valve.

Hiki ke hoʻololi i ka valve hoʻemi hoʻohaʻahaʻa hoʻohaʻahaʻa ʻekolu ʻaoʻao i ka valve pilote hoʻohaʻahaʻa lima maʻamau, ʻoi aku ka maʻalahi a ʻoi aku ka maikaʻi o ka mana ma mua o ka valve pilot manual. Hiki ke hana ʻia i loko o ka servo control manual multi-way valve e like me ka mea i hōʻike ʻia ma ka Figure 1. E like me nā hōʻailona hoʻokomo ʻokoʻa, ʻo ke kaomi hoʻohaʻahaʻa hoʻohaʻahaʻa e hana i ka piston hoʻopuka i ke kaomi ʻokoʻa a i ʻole ka kahe kahe e hoʻokō i ka mana proportional o ka neʻe ʻana o ka multi -ʻaʻa valve spool. ʻEhā-ʻaoʻao a i ʻole ka nui-way screw cartridge proportional valve e ʻae i ka mana o ka mea hana.
